i'm using Fedora Matespin since quite a while on my Wetab.
But since upgrading to Fedora 27/28 i can't reach the drop down menus in the taskbar with the touchscreen.
The menu drops but i can't choose anything with my fingers, just with a mouse.
Any other Touchscreen action works just fine and so i really don't know where to search.
Just checked the dconf editor without sucess.
Maybe somebody has the same or similar problem?
